Romero, who already has endured a lot of trash talk from the middleweight champion, expects to make him pay when they finally meet in the Octagon.

“This man spoke too much trash about me without knowing, because it was a supplement that was tainted,” Romero said on The MMA Hour. “He doesn’t know how hard I train, he doesn’t know how much I sacrifice to train hard. I sometimes give up time with my daughters to train. This man needs to pay.”

Romero is currently undefeated under the UFC banner, with his latest win coming over former UFC Middleweight Champion Chris Weidman at UFC 205. Romero believes that it was the winner over Weidman that has installed a sense of terror into the current middleweight kingpin.

“Have you seen that video on social media when I knocked out Chris Weidman and they got Bisping’s reaction of his face? It’s not fear, there are no words that explain that terror,” said Romero. “Have you seen those videos of people’s reactions when they’re at the beach and a tsunami rises? It’s the same expression that he had when I knocked out Chris. At that moment, he didn’t want to be the champion. At that moment he thought, ‘what am I doing fighting in this sport, what am I doing here? Look what’s coming now, why did I talk so much trash about this man?’”

Romero has earned a total of eight wins under the UFC banner and he hasn’t suffered a defeat in well over five years.
